Enclosures
The first decision when housing a rabbit or guinea pig is whether they should be kept inside or outside. Indoors, rabbits and guinea pigs are safe from predators and diseases spread by wild rabbits, whilst outdoor they can express natural behaviours such as grazing on fresh grass.
When housing rabbits indoors, you may find that rabbits are quite clean animals! Rabbits take well to litter training and can be allowed to free roam indoors with supervision. Ensure that your home is rabbit proofed as they tend to chew on objects including power cords!
Whilst guinea pigs can be litter trained, they do not readily take to litter training as easily as rabbits do and some may never use the tray.
Indoor enclosures should be set up in a temperature-controlled environment (ie not getting too hot or too cold), in a well-ventilated space, and with a cleanable floor covering. Usually, traditional hutches are not used indoors, but instead pens will be used. Rabbits are quite inquisitive animals, so the larger the space, the better. Rabbits should be able to stand on their back legs to stretch but not jump over the edges of the pen. Pens designed for rabbits are usually appropriate for guinea pigs as well, but it is best to check that the bars are appropriately spaced for a smaller animal. Separate food and water dishes should be provided, as well as a litter tray and somewhere for your pet to hide if they would like some privacy.
If housing rabbits and guinea pigs outside, a hutch is usually provided. Hutches should be large enough for the rabbit to stand on their back legs and hop at least four times from end to end (as above, most cages suitable for rabbits are a suitable size for guinea pigs). As with indoor pets, the larger the better to allow for exploration, exercise and enrichment. It is important to ensure that there is a well sheltered portion of the hutch where your rabbit or guinea pig is safe from weather extremes. Please be aware that wire-based flooring can be damaging to a rabbit or guinea pig’s feet (causing wounds and dermatitis) and should be avoided where possible, or the flooring covered with a layer or bedding such as straw, hay, newspaper or shredded paper. If utilising an outdoor hutch, it is recommended that rabbits are given supervised time each day outside of the hutch to properly stretch their legs and exercise. Guinea pigs are a little more sneaky and difficult to contain, so care is recommended (such as wearing a harness) if allowing them to free roam in the backyard.
Outside rabbits are also at risk of infections such as myxamatosis and calicivirus, and it is therefore recommended that rabbit enclosures are mosquito netted to reduce the risk of infection. Vaccination for calicivirus is highly recommended for any rabbits spending time outside.
